Definitions

  • FIGB United States Patent 3,432,016 MAGNETIC ROLLER CLUTCH Kurt Vogt, Bienne, Switzerland, assignor to Omega Louis Brandt & Frere S.A., Bienne, Switzerland Filed Aug. 30, 1966, Ser. No. 576,013 Claims priority, application Switzerland, Sept. 8, 1965,
  • the present invention relates to a free wheel coupling device for timepieces, including two coaxial elements, one of which is driving and the other is driven, one of said elements carrying at least one roller arranged in a notch and adapted to cooperate with a wall of the other element, so that the driven element is driven by the driving element only for one sense of rotation of the latter, said roller then jamming between both elements and interlocking said elements with each other.
  • This device is characterized in that the roller is a permanent magnet and the part of the other element cooperating with the roller is made of a magnetizable material, the element which carries the roller being made of a non-magnetizable material.
  • FIG. 1 is a top plan view, partly in section, of said embodiment showing the elements in driving position.
  • FIG. 2 is a similar view, showing the elements in nondriving position.
  • FIG. 3 is a cross-sectional view, at an enlarged scale, taken along the line IIIIII of FIG. 1.
  • FIGURE 4 is a view corresponding to FIGURES 1 and 2 but illustrating the inner surface of the rim as a cylindrical surface and illustrating a plurality of rollers.
  • the device illustrated in the drawing has two coaxial rotary parts.
  • the first rotary part, forming the driven element includes a disk 1 keyed onto a shaft 2 rigidly connected to a pinion 3.
  • the disk 1 has on its upper face a notch or cut out portion 4 open towards the outside and in which is disposed a roller 5, i.e. a cylindrical body of small height.
  • the notch 4 has the shape shown in FIGS. 1 and 2 and has a rounded bottom and two lateral flanks one of which extends almost radially, whereas the other extends chordally.
  • a toothed wheel made of two parts, i.e. a disk 7 and a rim or flange 8, the latter part being thicker than the disk 7 and partially facing the roller 5.
  • the roller consists of a permanent magnet the magnetic field of which is preferably perpendicular to the plane of the roller.
  • the rim 8 of the wheel 7, 8 is made of soft iron or another magnetiza'ble material.
  • the inner edge of the rim 8 as seen in a plan view, is festooned or scalloped, i.e. it is formed by a series of arcs of a circle the radius of which is equal to that of the roller 5, each arc of circle extending over about 80 and the centers of these arcs being placed within the rim 8.
  • the disks 1 and 7 are made of a nonferrous metal, for instance of brass.
  • the roller 5 is freely maintainedin the notch 4 of the disk 1 and is axially retained by the disk 7.
  • the festoons of the rim 8 might be omitted, the rim then having a mere cylindrical Wall 8a, which would also guarantee a sure jamming of the roller 5.
  • rollers instead of a single roller, two or more rollers might be provided, resulting in a balanced system with reduced backlash.
  • roller 5 it would also be possible to make the roller 5 of a magnetizable material, for instance of soft iron, and to have a rim 8 made of a permanent magnet. The operation would be the same as described above. In both cases, it is to be understood that the magnetic field is rather weak; it has to be just suflicient for overcoming the weight of the roller or rollers.
  • the device as shown and described is applicable for instance in the self-winding watches in which the main spring has to be wound up, whatever the direction of rotation of the winding weight may be, or in which the manual winding mechanism has to be rendered independent of the self-winding mechanism.
  • two coupling devices according to the invention may be used and are to be arranged either coaxially to each other or on different shafts.
  • a free wheel coupling device for timepieces comprising two coaxial elements, either one of said elements being adapted to be driven by the other of said elements, a roller, one of said elements having a notch carrying said roller and cooperating with a rim of said other element so that one element is driven by the other element only for one direction of rotation of the driving element, said roller then jamming between both said elements for the simultaneous movement thereof, characterized in that said roller is permanently magnetized and said rim of said other element is made of material forming a magnetic circuit with said roller, and said notch bearing element is a non-magnetizable material, whereby said roller is continuously held against said rim by magnetic flux passing mainly through said rim and said roller.
  • a free wheel coupling device in which said roller is disc shaped, its thickness being less than its diameter, the magnetic field being perpendicular to the plane of its fiat surface.
  • a free wheel coupling device according to claim 1 in which said notched element is the driving element.
  • a free wheel coupling device in which said rimmed element is the driving element.
  • a free wheel coupling device in which the inner surface of said rim is festooned.
  • a free wheel coupling device in which the inner surface of said rim is a cylindrical surface.
  • a free wheel coupling device in which a plurality of rollers are included.
